In this work we introduce and investigate the feasibility of "Simultaneous Multi-VENC" (SMV) imaging. This technique is inspired by "spokes" RF pulses used for parallel transmission and by Simultaneous-Multi-Slice (SMS) imaging. SMV enables encoding of a single 2D plane by two or more 2D phase images with different velocity sensitivities, allowing multiple encoding velocities (VENC). Only a single readout is used to acquire all VENC data, which are separated using a standard SMS slice-GRAPPA algorithm. The feasibly of SMV is demonstrated in a flow phantom and in-vivo for three spokes with two different VENC values.
